Not everyone hears subtle pitch differences equally. After listening
carefully it sounds like it may be <1 Hz difference, as in the advanced
stages of this test:
http://tonometric.com/adaptivepitch/
Listening to WWV 15 WPM code practive on 1802.5 last night, CW-L, 500 Hz,
AGC-F and AFX On or Off, the dashes are slightly higher in audio pitch (i.e.
lower in RF frequency) than the dots. It's easy to compare by listening to
your own code in the monitor, which does not have the issue.
This is not a big deal to me...just a curiosity but it's interesting that
others noticed it.
